Additional Notes

  • The BMW 600 carries a manual transmission fluid capacity of 1.25 liters, which is more than double the 0.6-liter figure shared by both Isetta variants, reflecting the 600's larger two-cylinder engine and more developed drivetrain architecture.
  • The 0.6-liter capacity listed for the Isetta 250 and Isetta 300 is a notably small fill volume, consistent with the single-cylinder motorcycle-derived transmissions used in microcar designs of that era.
  • BMW 600 fluid checks are specified at 2,000 km intervals, a considerably shorter inspection cycle than the 6,000 km check interval assigned to both Isetta models under normal use conditions.
  • The Isetta 250 and Isetta 300 share an identical service schedule, with fluid checks at 6,000 km and changes at 12,000 km under normal use conditions, despite spanning different production periods of 1955-1964 and 1957-1962 respectively.
  • The BMW 600 has a change interval of 16,000 km under normal use conditions, which is 4,000 km longer than the 12,000 km drain interval specified for both Isetta models.
  • All three configurations carry normal use condition designations, meaning the listed intervals are not adjusted for severe operating environments such as extreme temperatures, heavy loads, or frequent short trips.
